Off the top of my head the most consistent streamers who upload daily hearthstone content on Youtube that I know are Kripparrian, Amaz, Trump, Kolento, Thijs, Kibler, Savjz, Strifecro and Firebat. They all have different personalities and even though I watch all of them, they are not all going to be to everyone's taste so just check them out and sort out the ones that you like.
